The first four images show a round-shaped area characterised by intermediate signal intensity on T2-weighted imaging (a), restricted diffusion on DWI (b) and in the ADC map (c), and ring enhancement (d). These findings, together with clinical history, orient towards the diagnosis of abscess. The other four images show a focal nodule in the right anterior peripheral zone, characterised by low signal intensity on axial T2-weighted imaging (e) with sharply defined margins and tiny bright spots, and restricted diffusion on DWI (f) and in the ADC map (g), and homogeneous enhancement on DCE imaging (h). These findings are consistent with an ectopic nodule of BPH
